Not too advanced for those accustomed to using such tools. Actually more functional considering the leverage in downward pressure opposed to the leverage used in long handled knives humans in modern societies have been accustomed to. Only draw back one would need to switch tools for use of small point penetration. Defiantly in the right application it's more than functional.
